the mammals of the islands.^ Twenty-eight land mammals have 

 been recorded as actually represented by specimens, though 

 several others are mentioned which the collectors ascertained to 

 occur. Dr. Abbott secured forty-four species, but failed to ob- 

 tain seven ^ of those previously taken. The total number of 

 mammals collected on the islands thus becomes fifty-one. This 

 increase is due, in part to the recognition of a larger number of 

 insular forms than has been admitted by previous writers, but 

 also to a considerable extent to the actual addition of species 

 not hitherto taken. Species new in the latter sense are distin- 

 guished in the present paper by absence of reference to pre- 

 vious records. 



In regard to the faunal relationships of the Natunas, whether 

 predominantly Bornean or Peninsular, about which much has 

 been written,^ it may be said that this collection, together with 

 much of the other work recently done by Dr. Abbott, tends to 

 show that there is greater general uniformity in the mammalian 

 fauna of Borneo, the Malay Peninsula, and the intervening 

 islands than has been hitherto supposed. It seems unprofitable 

 therefore to offer conjectures as to the probability of greater 

 nearness of the Natuna mammals as a whole to those of Borneo 

 or to those of the Malay Peninsula.

 mal described, though supposed to have been taken in Borneo, is apparently con- 

 fined to Bunguran Island, the largest of the Natunas.
